To determine whether a problem is being caused by missing bootloader firmware, examine the device for
the following symptoms:
1) MLB LEDs: Power on the device and observe the LEDs on the edge of the MLB facing the left side
access door. In normal operation, the green LED D1 is solid for 10-20 seconds during power-up
initialization, then begins blinking. If D1 does not turn on at all, as shown below, the MLB no longer
has working bootloader firmware and must be returned to MagTek for service.
2) Touchscreen / External Controller: After a period of time, the touchscreen or external controller
PC’s display pops up an error dialog box reporting Unable to start the MTECJobServer. If an
operator presses the OK button to close the dialog box, the touchscreen reports Offline as the device
status, and Error Opening Controller as the reason.
3) Remote Host: A host sending transactions to the device using the network API receives responses
containing Return Code 65, Error Opening Controller.
4) If the device is exhibiting these behaviors, contact MagTek Support Services to make arrangements
for RMA rework or replacement.
There is a related case where the device’s firmware has become corrupted and must be reloaded, but the
bootloader is still intact. This can generally be fixed in the field using the touchscreen or external
controller PC and standard firmware update procedures, and does NOT require a return RMA. This
behavior is different from the missing bootloader symptoms above:
1) MLB LEDs: D1 on the MLB begins blinking immediately on power-up, instead of being
permanently off (missing bootloader) or solid for 10-20 seconds (normal operation).
2) Touchscreen / External Controller: The touchscreen or controller PC’s display reports Offline as
the device status, and Eject Bin Full as the reason, even when there are no cards in the card output
bin or in the card rejection bin. In the case of firmware problems, this indicates the software is having
difficulty using the MLB to enumerate the status of all the device’s sensors.
3) Remote Host: A host sending transactions to the device using the network API receives responses
containing Return Code 28, Eject Bin Full.
4) If the device exhibits all these symptoms, reload the device’s firmware. See the ExpressCard service
manual D99875607, section Update the Firmware for details.
